DX GeoThermal HVAC Systems

Has anyone any experience with “DX” Direct Exchange GoeThermal Systems? They use copper tubes filled with R22 buried rather than closed plastic loops of more standard geothermal systems. Two manufactures that I am aware of are American GeoThermal http://www.amgeo.com/ and ECR Technologies http://www.ecrtech.com/
